1 General Information and Safety
1.1 Safety notes
Before starting the ACR 300i, read these instructions carefully, ensure that you have understood them and comply
with them at all times.
The ACR 300i should only be connected by a qualified electrician.
Do not tamper with or make alterations on the unit!
The ACR 300i is not a safety-critical component and its use is prohibited under conditions where the safety of persons may depend on its function.
The IP address set for the ACR 300i should be marked on the enclosed label. After installation, stick the label on the
sensor in a clearly visible position.
The IP address of the ACR 300i must be used once only in any network.
For use with any listed (CYJV) cable assembly.
1.2 Components supplied
l ACR 300i including integrated illumination (or as version with C-Mount lens without illumination)
l CD-ROM with Computer software and Operating instructions
l Data sheet, mounting clamp, allen key, screwdriver and protective cap for Ethernet plug.
1.2.1 Software Setup Download
The PC Software Setup is also available at www.leuze.com/en/usa in section Download/Software.
In order to reduce the size of the installation files two setup files are provided:
1. ACR 300i_PC-Software_VX_X_X_X.exe:
This is the regular setup file, containing the current software release. This is valid for all vision sensors with
firmware version 1.18.X.X or higher.
1.3 Requirements for use
Configuration of the ACR 300i requires a standard PC/notebook (at least Pentium 4, 1GHz and 1 GB RAM, with
Microsoft Windows 7 or Windows 10) with network connection or a network with TCP-IP protocol. We recommend a
Pentium 4 Dual Core > 2GHz and 2GB RAM, for Windows 7 or Windows 10. We recommend a screen resolution of
min. 1024 x 768 pixels. A basic knowledge of computers is also required. The ACR 300i is supplied with the IP
address 192.168.100.100 and a subnet mask 255.255.255.0. The ACR 300i is operated independently of a PC or
PLC. A PC/notebook is only necessary for configuration of the ACR 300i. Attention must be paid to sufficient and
constant object illumination to ensure reproducible results and avoid malfunction. Reflections or varying incident light
may affect detection results. If necessary, use an external light source and/or light-screening / shrouding devices to
exclude incident light.

Leuze electronic
2 Intended Use
2.1 Field of application
The ACR 300i is an optical sensor and uses several evaluation methods according to the version: pattern recognition,
contrast detection, brightness, BLOB, caliper, gray level, contour detection, barcode or Data Matrix code reading,
Optical Character Recognition. The product is designed for industrial use only. In residential areas it is possible that
additional measures for noise suppression must be done.
Code Reader:
Identification of products, components or packaging from printed or directly marked – punched or laser-etched –
codes is common practice in many sectors of industry today. The ACR 300i Code Reader from Leuze electronic
immediately detects which part is in front of it: it can easily read numerous types of barcodes as well as printed and
directly marked data matrix codes according to ECC 200 standard and read characters directly via Optical Character
Recognition (OCR), and this on any base (metal, plastic, paper, glass). The sensor can even routinely decipher
askew or warped codes or codes on convex, reflective or transparent surfaces. The ACR 300i Code Reader
assesses the quality of your printed or directly marked data matrix codes using standardised ISO and AIM quality
parameters. This enables you to introduce early correctional measures and thus avoid rejects due to illegible codes.
ACR 398i
In addition to the ACR 368i, the ACR 398i has additional functions and is also available as a color variant.
The ACR 300i range is an economic alternative to conventional image processing systems.

3 Installation
3.1 Mechanical Installation
To ensure maximum accuracy of detection, the ACR 300i should be protected from vibration. Secure the supply and
I/O cables with cable binders to prevent crushing or slipping.
Select a position for the ACR 300i in which interfering factors such as slight differences in the position of the object or
variations in illumination have little or no effect.
Screw the ACR 300i onto the mounting clamp (supplied with the unit) and then onto a suitable object. Use only the
Mounting bracket MB-2 300 (no. 50136487) or the Mounting hinge MB-1 300 (no. 50136486).
3.1.1 Arrangement for dark-field illumination

3.1.2 Arrangement for bright-field illumination
For transmitted light/measuring tasks or for the accentuation of highly-reflective objects
Fig. 4: Arrangement for bright-field illumination
Observe the object clearance given in the table Field of View / Working Distance. To avoid interfering reflection from
the detection object, align the ACR 300i at an angle of approx. 10°- 15° with reference to the optical axis.
Fine adjustment
Important: Fine adjustment of the ACR 300i should not be carried out until after electrical connection and start-up (PC
software installation).

3.1.3 Alignment for a vertical illumination
In order to assure the absolutely vertical alignment of the ACR 300i to the object surface, put a piece of reflective foil
or a mirror on top of the object and start the ACR 300i operating software. For an image that is continually updated,
select trigger mode “Free run” and image update: “Continuous”. Then align the sensor to the reflective surface / the
mirror as vertical as possible until the integrated illumination LEDs are directly dazzling in the image of the user interface (Arrangement for bright-field illumination (Page 21)).

For fixing the ACR 300i on a fixing system / machine housing, slide the provided dovetail Mounting bracket MB-2 300
on the dovetail guide at the bottom side of the ACR 300i and fix it at the desired position with the hexagon socket in
the cross hole of the mounting bracket. Then additional Leuze electronic mounting accessories may be attached to
the mounting bracket or any other attachments may be fixed by using the tapped holes in the Mounting bracket MB-2
300.
3.2 Electrical installation
The electrical installation of the ACR 300i must be carried out by a qualified person. When installing the ACR 300i,
disconnect all electrical components from the power supply. When the unit is being used in a network, ensure that the
network address (IP address) of the ACR 300i set by the manufacturer at 192.168.100.100 is free and is not in use for
any other unit connected to the system. If necessary, re-set the IP address of the ACR 300i as described in the section “Network settings”. When the ACR 300i is in use, the protective caps supplied must be pushed onto the M12
sockets (data and LAN) which are not in use. For error free operation the length of the connecting cables must not be
longer than 30 m. Failure to do this may cause malfunction.

3.3 Network settings, Short reference
The following instructions indicate how to change the network configuration of the PC and the ACR 300i. If incorrect
settings are used, the network connections in the computer may be lost. To be on the safe side, note the former settings for later use if required. Following this procedure, it may be necessary to re-start the system. In order to determine which IP addresses are allowed in your network or locally in your PC, and to carry out the necessary settings on
your PC, contact the system administrator beforehand. The illustrations, dialogues and menus originate from the operating system Microsoft WindowsXPTM. The illustrations are similar in other operating systems.
See chapter: Basic settings for PC and ACR 300i
3.3.1 Basic settings for PC and ACR 300i
To configure the ACR 300i with a PC it is essential that a network board and the TCP/IP LAN- connection is installed
on the PC (This also applies when the PC is not connected to a network). The ACR 300i supports the automatic
recognition of the Ethernet transmission rate, but 100 MBit at the most. The internet protocol IPv4 must be activated.
There are two alternatives to configure and parameterize the ACR 300i.

3.3.2 Direct Connection - Setting the IP Address of the PC
To connect the ACR 300i to a PC via Ethernet the IP addresses of both devices have to correspond. The default IP of
the ACR 300i is 192.168.100.100 with Subnet mask = 255.255.255.0. To establish a direct connection, the PC must
be set to a corresponding, fixed IP address like follows.
1. Click on Start / Control Panel / Network Connection / LAN Connection / Properties, the window “Local Area
Connection Properties” opens.
2. In the list “This connection requires following elements” select the option “Internet Protocol (TCP/IP)” and then
click the button “Properties”.
3. In the following window (see fig. 7) set the desired IP address of the PC and the sub-network data.
4. Confirm entries with OK.
Example:
The ACR 300i is pre-set to IP address 192.168.100.100 and subnet mask 255.255.255.0.
In this case, the IP address may be set to any value between 192.168.100.1 and 192.168.100.254, with a subnet
mask 255.255.255.0, with the exception of the sensor IP address (192.168.100.100).
To alter the sensor’s IP address, see chapter: Sensor's network settings (Page 51). Please do also not use the
addresses .0 and .255 as these addresses are reserved for network infrastructure devices such as servers, gateways, etc.
